Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack

Overview

The Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack offers builders three complete frame and jig assemblies for serial-number-free firearm construction. Each kit contains an unfinished 80% polymer frame paired with a dedicated jig system, allowing end users to complete the frame through machining of the trigger housing pocket and pin holes. This 3-pack configuration provides consistent build geometry across multiple units, ideal for those requiring repeatable results from a single procurement lot. The frames are manufactured from reinforced polymer with molded-in indexing points for precise alignment during the finishing process.

Each PF940Cv1 frame in this 3-pack accepts standard Glock 19 and Glock 23 Gen3 upper assemblies, lower parts kits, and magazines. The jig included with each kit uses hardened steel drill bushings to maintain bit alignment during pin hole drilling. The 80% frame requires completion by the end user and is not a finished firearm. No serial number is applied by the manufacturer.

Who It’s For

This 3-pack of the Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) suits experienced firearm builders requiring multiple consistent frame blanks for personal projects or instructional use. It is appropriate for individuals who have completed at least one previous 80% frame build and understand the machining operations necessary to finish the frame. Builders should possess a drill press or hand drill with steady control, as the jig relies on operator precision for pin hole placement. This product is not intended for first-time builders unfamiliar with frame finishing procedures.

• Recommended for: advanced hobbyists, instructors, and builders producing multiple identical frames
• Not recommended for: first-time 80% builders without prior experience in polymer frame finishing
• Tools required: drill press or hand drill, end mill (included), deburring tool, and calipers for depth verification
